Yet Another Ring Buffer

SPSC channel backed by a ring buffer.

The channel is optimized for sending and receiving bytes - it has several features allowing to produce and consume items in bulk. This makes it suitable for implementing an intra-process pipe stream. However it may be used with other types as well.

Features include:

• Lock free, non-blocking push and pop, with no allocation and O(1) time.
• If desired, can integrate blocking, futures-based, or custom waiting. If undesired, no-op waiters add no overhead.
• view functions for safely accessing the buffer directly, ex. for doing IO directly from or to the buffer.
• no_std compatible (currently requires alloc)

Does not support:

• Multiple producers or consumers. The view API would make this challenging. If you don't mind a lack of concurrency, you can wrap the ends in a Mutex though.
• Dynamic resizing
